NAME
       bind_textdomain_codeset - set encoding of message translations

SYNOPSIS
       #include <libintl.h>

       char * bind_textdomain_codeset (const char * domainname,
				       const char * codeset);

DESCRIPTION
       The  bind_textdomain_codeset function sets the output codeset for mes-
       sage catalogs for domain domainname.

       A message domain is a set of  translatable  msgid  messages.  Usually,
       every software package has its own message domain.

       By  default,  the  gettext family of functions returns translated mes-
       sages in the locale’s character encoding, which can  be	retrieved  as
       nl_langinfo(CODESET).  The  need	 for  calling bind_textdomain_codeset
       arises for programs which store strings in a  locale  independent  way
       (e.g.   UTF-8)  and want to avoid an extra character set conversion on
       the returned translated messages.

       domainname must be a non-empty string.

       If codeset is not NULL, it must be a valid encoding name which can  be
       used for the iconv_open function. The bind_textdomain_codeset function
       sets the output codeset	for  message  catalogs	belonging  to  domain
       domainname  to  codeset.	 The  function	makes  copies of the argument
       strings as needed.

       If codeset is NULL, the function returns the  previously	 set  codeset
       for  domain  domainname.	 The  default  is NULL, denoting the locale’s
       character encoding.

RETURN VALUE
       If successful, the bind_textdomain_codeset function returns  the	 cur-
       rent  codeset  for  domain domainname, after possibly changing it. The
       resulting string is valid until the next bind_textdomain_codeset	 call
       for the same domainname and must not be modified or freed. If a memory
       allocation failure occurs, it sets errno to ENOMEM and  returns	NULL.
       If no codeset has been set for domain domainname, it returns NULL.

ERRORS
       The following error can occur, among others:

       ENOMEM Not enough memory available.

BUGS
       The return type ought to be const char *, but is char * to avoid warn-
       ings in C code predating ANSI C.
